Shreaded Clam Shells
On Memorial weekend we had a family reunion. The main course was sea food consisting mostly of clams, followed by crab, then lobster. I collected up 4 bags of shells with some corn cobs thrown in. Last week I shreaded the shells and cobs to wind up with 3 five gallon buckets of material. My thought is that this material should be good for the garden. My question is has anyone had experience with crushed shells and how much is useful? Thank you in advance for your input.
As a side note. Discovery channel did a short piece on Kingsford charcoal. The formula was stated as: hardwood sawdust with some anthracite coal baked at 1000 degrees, corn gluten for glue and lime to give a white color after burning.
